' Application January 3,

3 Claims.

This invention relates to a metatarsal arch support having means for detachably securing it to the inner sole of a shoe in any desired position relative to the sole, and has for its object to provide a simple durable and effective support including a pad and improved means for adjustably supporting the same so that the pad is capa' ble of rotative adjustment about a center which T is adapted to be variously located in a fixed position, and capable also of rectilinear adjustment on said center. I

Of the accompanying drawing forming a part of this specification,-

Figure 1 is a top plan view of a shoe having my improved support, and illustrates rectilinear adjustments of the support.

Figure 2 is a view similar to Figure 1 illustrating rotative adjustments.

Figure 3 is an enlarged top plan view of the support.

Figure 4 is a section on line 44 of Figure 3.

Figure 5 shows in perspective the slotted plate shown by dotted lines in Figures 1, 2 and 3.

Figure 6 is an end view, and Figure '7' a sectional view of the rivet shown by dotted lines in Figures 1, 2 and 3.

Figure 8 is a sectional View showing a differently formed rivet.

Figure 9 is a section on line 9-9 of Figure 3.

The same reference characters indicate the same parts in all of the figures.

In the drawing 12 designates a pad of compressible and preferably resilient material such as sponge rubber, having a bottom face conformable to the top face of an inner sole l3, and a convex top face sloping outward and downward from its central portion to the margin of the bottom face, said central portion being relatively "thick.

The pad is preferably provided with a flexible casing member 14 covering its top face, and a flexible casing member 15 covering its bottom face, said casing members meeting and being secured together around the margin of the pad.

I provide improved adjustable securing means for slidably and rotatively connecting the pad with any desired portion of the inner sole. The elements of said means are a rivet composed of a head 16 embedded in the thicker portion of the pad, and a preferably tubular shank 1'7 projecting from the head below the bottom face of the pad, and an anchoring plate 18 preferably of thin sheet metal having means such as prongs l9 separably engageable with different portions of the inner sole to prevent movement of the plate rela- Rockland, Mass.

tive to the sole, said prongs being adapted to penetrate the sole.

The plate has an elongated slot 20 receiving the rivet shank. Said shank has an enlargement 21 preferably formed by upsetting the lower end of the rivet, said enlargement bearing on the under side of the plate at opposite edges of the slot, and pressing the plate closely against the bottom face of the pad, or the bottom casing member 15.

A portion of the pad is located above the rivet head and is of sufiicient thickness to cushion the rivet.

The lower portion of the pad underthe rivet head is compressed by the rivet to frictionally oppose accidental movementsof the pad.

The rivet is rotatable in the slot, and is also movable lengthwise thereof so that the rotative adjustment'shown by Figure 2 and the rectilinear adjustment shown by Figure l are permitted.

As shown by Figure 8, the rivet shank 17 may be bifurcated to facilitate the formation of the enlargement 21 which in this instance is formed by the bifurcations of the rivet.

The pad is preferably provided with an orifice 22 extending downward from its central portion to receive a wire nail, an awl, or other device, used in exerting force on the pad to adjust it rectilinearly. The orifice may be arranged so that the bore of the rivet l7 constitutes an extension thereof as'shown by Figures 3 and 4. Rotative adjustments of the pad may be conveniently effected by pressure of a hand on the pad.

I claim:

1. A variously adjustable arch support including a pad of compressible material having a bottom face conformable to the top face of an inner sole and a convex top face sloping outward and downward from its central portion to the margin of the bottom face, said central portion being relatively thick, and adjustable securing means for slidably and rotatively connecting the pad with any desired portion of an inner sole, said means comprising a rivet composedof a head embedded in the thicker portion of the pad, and a shank projecting from the head below the bottom face of the pad, and an anchoring plate having means separably engageable with different portions of an inner sole toprevent movement of the plate relative to the sole, and an elongated guiding slot receiving the shank, the latter having an enlargement bearing on the under side of the plate at opposite edges of the slot ands?v pressing the plate closely against the bottom face of the pad, a portion of the pad being above and pad having a flexible casing member covering its top face, and a flexible casing member covering its bottom face.

3. An arch support as specified by claim 1, the pad being provided with an orifice in its central portion to receive an adjusting device.
